What is the optimal time for a scuba diver to be on the bottom of the ocean? That depends on the depth of the dive. The U.S. Nav

y has done a lot of research on this topic. The Navy defines the "optimal time" to be the time at each depth for the best balance between length of work period and decompression time after surfacing. Let x = depth of dive in meters, and let y = optimal time in hours. A random sample of divers gave the following data. x 14.1 24.3 31.2 38.3 51.3 20.5 22.7 y 2.68 2.18 1.48 1.03 0.75 2.38 2.20

Which monomial is a perfect cube? 49p9q3r24 81p12q15r12 121p9q3r6 343p6q21r6.
Makovka662 [10]

The monomial is a perfect cube is \rm 343p^6q^{21}r^6.

<h3>Perfect cubes;</h3>

Perfect cubes are the numbers that are the triple product of the same number.

We have to determine

Which monomial is a perfect cube?

A perfect cube monomial must have three identical roots, such that the product of the roots equals the perfect square monomial.

It must be possible for the coefficient of a perfect cube monomial to be written in the form n3, where n equals the cube root of the coefficient.

A perfect cube monomial must have exponents on the variables.

Then

The monomial is a perfect cube is;

\rm= 343p^6q^{21}r^6\\\\= \sqrt[3]{  343 }= 7

Hence, the monomial is a perfect cube is \rm 343p^6q^{21}r^6.
